Abstract: The overhead associated with establishing and operating the link is a major source of inefficiency in millimeter wave communication systems.
One significant source of overhead is the time spent training the transmit and receive beams, which occurs during estimation, feedback, channel tracking. Fortunately, there is side information available through sensing or communication available in bands outside of the millimeter wave communication band. This talk explains the why beam configuration in millimeter wave systems is a major source of overhead.
It then shows how out-of-band information can be used to reduce that overhead. Different types of out-of-band data are described including position, channel state information derived from another communication band, and sensing in the form of radar and video. Examples of the application of out-of-band information are shown including leveraging inverse finger printing and weighted compressed beam training.
Bio: Nuria González Prelcic is currently an Associate Professor in the Signal Theory and Communications Department, University of Vigo, Spain. She has held visiting positions with the University of New Mexico (2011), and The University of Texas at Austin (2014, 2015 and 2016). Her main research interests include signal processing theory and signal processing for wireless communications: filter banks, compressive sampling and estimation, multicarrier modulation, channel estimation and MIMO processing for millimeter wave communications. In the last 3 years she has co-authored around 30 journal and conference papers in the topic of signal processing for MIMO systems with large arrays. She has published a tutorial in the IEEE Journal of Selected Topics in Signal Processing. She has also served as guest editor for the special issue of this journal on signal processing for mmWave wireless communications and is currently an Associate Editor for IEEE Transactions on Wireless Communications. She has delivered tutorials on millimeter wave communications at Globecom 2016, WCNC 2017 and ICASSP 2017. She has been the founding director of the Atlantic Research Center for Information and Communication Technologies (AtlantTIC) at the University of Vigo from 2010 to 2017.
